CROSS-REFERENCE TO RELATED APPLICATION

Pursuant to 35 U.S.C. § 120, this application is a continuation of U.S. patent application Ser. No. 15/666,841, entitled “A SYSTEM AND METHOD FOR CONDUCTING A DRONE RACE OR GAME,” filed Aug. 2, 2017, and naming Rebecca Noah Poynter and Ronald J. Poynter as inventors, which is a non-provisional of U.S. Provisional Patent Application No. 62/370,552, filed Aug. 3, 2016, naming inventors Rebecca Noah Poynter and Ronald J. Poynter, and entitled “A SYSTEM AND METHOD FOR CONDUCTING A DRONE RACE OR GAME,” each of which is incorporated by reference herein in its entirety for all purposes.

FIELD

The present invention relates to the operation of a drone race, and, more specifically, to a system and method for conducting a drone race or game in a contained or designated area(s), indoor or outdoor.

BACKGROUND

An unmanned aerial vehicle (hereinafter “UAV” or “drone”) is an aircraft designed for flying without a human pilot on board. UAVs are used in various industries and capacities. For example, UAVs are currently being used for reconnaissance, particularly in military operations, and some private companies are experimenting with UAV technology to deliver packages. Further, decreasing costs of UAVs and related equipment has resulted in the growth of UAV hobbyists. Currently, UAVs may be remotely piloted by human pilots who may be located in the general vicinity of the aerial vehicle, or halfway around the world.

Because drones are available to the public and are increasingly popular with hobbyists, there becomes an increasing need for areas dedicated to drones, specifically for drone races. The Federal Aviation Administration (FAA) has a list of requirements for drones flown for recreation:

-   -   If the drone is flown outdoors, the drone must be registered if         over 0.55 pounds,     -   the drone must be flown 5 miles from airports without prior         notification to airport and air traffic control, and if the         drone is flying within 5 miles of an airport, the operator must         notify the airport and the air traffic control tower,     -   The drone must yield right of way to manned aircraft,     -   The drone must kept in sight (visual line of sight),     -   The drone must be less than 55 pounds, and     -   The operator must follow community-based safety guidelines.

The FAA website also provides a list of airspace restricted areas, such as stadiums, areas in or around a wildfire firefighting operation, and within the greater Washington, D.C. area. Therefore, there is a need to create an area capable of conducting a drone race or game while keeping in mind restrictions set down by the FAA.

Another concern for current drone racing systems is the matter of how spectators will view the race. There is a need to create a system for conducting a drone race or game that allows spectators to view the drone race.

Choice of hardware and implementation is considered within the skill of one of ordinary skill in the art for which the invention applies.

With reference to FIGS. 1-14, but particular emphasis on FIG. 1, a top view is shown of an exemplary embodiment of a drone racing system 2, such as a system for a drone race in a contained area, and with particular emphasis on FIG. 2. a side view is shown of the exemplary embodiment of the drone racing system 2. The drone racing system 2 for conducting a drone race has multiple drones 4 following a race track, and the race track has multiple obstacles, flags, and/or information points to increase the difficulty of the race, such as pylons 6 and hoops 8 and gates. In various embodiments, the drones 4 are tagged with temporarily attached RFID tags, or other types of temporary sensors such as an RF transmitter 31, such as a video transmitter 31 emitting radio frequency energy. The obstacles, in turn, are attached to RFID tag readers, or other types of sensor readers such as a receiver 32 to detect the intensity, the change of intensity, and/or the content of the radio frequency energy emitted by the RF transmitter(s) 31. When a drone 4 with a temporarily attached RFID tag and/or RF transmitter 31 passes through or near one of the obstacles placed along the race track, the tag reader and/or RF receiver 32 will detect the RFID tag and/or radio frequency energy as the drone 4 passes by and transmit this information to a race server 1206 that monitors the drone race. The race server 1206 uses the information from the tag readers and/or RF energy to determine the race position of each drone 4 in the drone race. For example, a detected radio frequency energy may increase in amplitude as a drone 4 approaches a receiver 32 and decrease in amplitude as the drone 4 travels away from a receiver 32 so that the point of inflection (e.g., the peak amplitude) coincides in time with a closest approach of the drone 4 to the receiver 32. Video receivers 10 or video cameras may be set up around the contained area of the drone race to capture video of the drone race. An overhead camera 11 may be set up above the race course and looking downward to allow determination of relative positions and/or progress through the course of drones 4 and/or to view the entire race course.

Obstacles of the drone race system may be pylons 6, flags, hoops 8, or any designated structure or information points and have attached sensor readers and/or radio frequency receivers 32 for tracking the drones 4 of the drone racing system 2. The obstacles may comprise other shapes and sizes and placed at various positions on the race track to increase or decrease the difficulty of the drone race. The obstacles may be constructed to improve portability so that the obstacles may be transported from one contained area to another contained area, or moved within the contained or designated area. The sensor readers and/or radio frequency receivers 32 attached to the obstacles may be attached anywhere on the obstacles to effectively detect the sensor temporarily attached to the drones 4 and/or detect changes in the characteristics (e.g., content and/or amplitude) of the radio frequency energy transmitted by the drones 4 as they pass by or pass through the obstacles on the race track of the drone racing system 2. The sensor readers may use any type of communication channel to communicate with the race server 1206, such as, as mentioned, detecting changes in the characteristics (e.g., content and/or amplitude) of the radio frequency energy transmitted by the drones 4.

In one embodiment of the drone racing system 2, the temporary sensor may be RFID tags and the sensor readers can detect RFID tags. Other types of sensors and sensor readers that may be implemented with the drone race system are QR tags and QR readers, magnetic stripes, Bluetooth transmitters and receivers, or wireless tracking systems, for instance, a radio frequency transmitter 31, such as a video transmitter 31 serving as the so-called sensor and a radio frequency receiver 32 capable of detecting an amplitude of a signal transmitted by the radio frequency transmitter 31 serving as the so-called sensor reader.

According to another embodiment of the drone race system, virtual information points may be positioned at various locations along the race track and/or within the contained or designated area. These virtual information points may be customized, and information points may be individual and specific to an individual drone race or game. Once a drone 4 enters a prescribed radius of the information point, the drone racing system 2 triggers an alert and may prompt the pilot of the drone 4 for action. The prompt to the pilot may comprise a question presented to the pilot via a computing device synchronized to the drone 4. Alternatively, the prompt may comprise a GPS location for a new location in the contained or designated area, so as to lead the pilots on a scavenger hunt. The trigger and prompt process for the virtual information points may be customized to suit the requirements or specifications of each drone race or game.

Cameras may be attached to the drones 4 participating in the drone race. The cameras may capture live streaming footage of the drones' surroundings, or alternative, may capture live streaming footage of the environment in front of the drone 4. The cameras attached to the drones 4 may be any type of camera suitable for drone 4 racing or for transmitting live streaming footage with accurate and clear reception. Video receivers (such as antennas) 10 may be positioned on the edges of the contained area to receive transmissions from the drones 4 of the drone race, including the camera video transmissions. As mentioned video receivers (such as antennas) may be positioned along the race course, such as on pylons 6 or hoops 8.

In an alternative embodiment, transceivers may be positioned on the edges of the contained area to transmit instructions from the pilots of the respective drones 4 through the computing device corresponding to each drone 4. The transceivers may be any electrical device capable of receiving and transmitting information and/or data from the sensor readers, the drones 4, the pilots' computing devices, and/or the race server 1206.

The computing devices of the drone racing system 2 may include smartphones, tablets, laptops, desktops, or any other type of electrical device capable of processing program instructions for performing a certain task. In one embodiment, the computing devices may comprise an application designed to communicate with a drone 4. Each computing device corresponds to one drone 4, and the pilot uses the application of the computing device to monitor the movements of the drone 4. The application of the computing device may receive the video transmissions from the camera of the corresponding drone 4 and display the video transmissions from the drone camera with a drone pilot controls overlay.

The video transmissions from the drone cameras may be transmitted to FPV (first person view or first person video) goggles. The drone 4 may be set up to facilitate the use of FPV goggles. The use of FPV goggles simulates an immersive first-person experience, as if the pilot was actually sitting in the cockpit of the drone 4. FPV goggles may also be available to spectators to view different perspectives of the drone race. Alternatively, the video transmissions from the drone cameras may be available to view via a web/internet-based application for spectators and/or may be viewed on a tablet or other mobile devices as desired.

Participants of the drone race system may register online with the race server 1206. Online registration may include calibrating the participants' computing device to monitor and/or a drone 4 of the drone racing system 2. The online registration process may take in the participants' names, personal information, drone information, and social media information, and may synchronize with an account on the race server 1206 or on an application.

With reference to FIGS. 1-14, but particular emphasis on FIG. 3, a side view is provided of an exemplary embodiment of a drone racing system 2 for a drone race in an indoor contained area. When installed in an indoor contained area, the system may include an overhead camera 11 for an overhead view of the drone race, and further supplements the video displays for spectators and for the pilot participants of the drone race.

With reference to FIGS. 1-14, but particular emphasis on FIG. 4 and FIG. 5 exemplary embodiments are shown of a leader board of the drone race or game system. The leader board is a scoreboard showing the names and current information about the competitors. FIG. 4 illustrates a leader board 13 with four competitors 14-1, 14-2, 14-3, and 14-4, and shows information such as the name 15 of the drone 4, the time 16 elapsed between the drone 4 passing from the second to latest gate to the latest passed gate, pylon or hoop, the average time 17 the drone 4 takes to make a single lap, and the total time 18 from the start of the race to the present time. The information may include aspects such as maximum speed, fastest lap, average speed, etc. The information of the leader board 13 is updated, for instance, on demand, periodically, or continuously, to show current information, and the information of the leader board 13 may be shifted up or down to reflect a drone's current place in the drone race or game. The leader board 13 may optionally show the live feed 19 from the drone camera, or the video transmission that a FPV goggle would receive. The leader board of FIG. 4 shows also the a graphical and dynamic view of the race track 20 (e.g., “Dynamic Graphical Map”) generated by the drone race or game system to take into account drone speed, time at each gate, and other data to calculate the position of the drone 4 in the race. This graphical dynamic view of the race track, like the rest of the leader board, updates, for instance, on demand, periodically, or continuously, to show current status of the drones 4. In various instances, the Dynamic Graphical Map may comprise a three-dimensional representation of a race course that may be viewed by drone operators, spectators, and/or third parties, such as via an electronic device running an application. Additionally, the leader board may comprise an overhead view 21 of the race track from an overhead camera. The leader board scores may be used in a community ranking for race or game participants available on a web or internet based application.

Shifting particular emphasis to FIG. 6, another exemplary embodiment of a leader board 22 is shown with enlarged views of video feeds 19 from the drone cameras. FIG. 7 depicts an exemplary embodiment of another leader board 23 that shows split screen views 24 of the participating drones 4 with limited information about each drone 4 such as name 15 and total time 18. FIG. 8 illustrates an exemplary embodiment of a leader board 25 that displays only two video feeds of the participating drones 4. In this exemplary embodiment, the leader board may cycle through the various video feeds of the participating drones 4, so as to provide all status information of the drones 4 and to provide enlarged views of the drones' video feed. Alternatively, the leader board may display photo or video feed of an information point along the race track, which may in various instances may be provided by the system to electronic devices, such as mobile devices such as for real-time or near real-time viewing by spectators.

In another embodiment of the present invention, the leader board may be synchronized with an online community with times displayed for pilots and/or participants. The online community may be hosted separately from the drone racing system 2, but may be designed to communicate with the drone racing system 2, so that for any past, ongoing, or future drone race or game, the online community may be updated with the scores and race/game information. Members of the online community do not necessarily have to be participants or pilots (former or current) to participate in the online community. The online community provides a forum for participants and pilots to interact, and the online community may be viewed or used via an application on a computing device.

Focusing primarily on FIG. 9, an exemplary embodiment is shown of the drone racing system 2 for conducting a drone race or game using data tags 26 such as bokodes, barcodes, QR codes, etc. For instance, data tags 26 may further comprise energy emission or receiving mechanisms, such as receivers 32 to detect the presence and/or strength of a radio frequency transmission from a drone 4, for instance, from a video transmitter 31 on the drone 4. FIG. 10 illustrates elements of the exemplary embodiment of the drone race or game system for conducting the drone racing system 2 using data tags 26. The drones 4 of the drone racing system 2 may be set up with cameras 27 or sensor readers, such as low light IR drone cameras 28, capable of detecting and processing data tags 26, such as a daytime QR code 29 or nighttime QR code 30. Alternatively the drones 4 of the drone racing system 2 may be set up with transmitters 31, such as video transmitters 31, capable of being detected by a receiver 32 emplaced to serve as a so-called data tag 26. These aspects such as data tags 26 may be set up at specific points in a contained area, and the pilot controls the drone 4 to each specific point where the drone 4 will detect and process the data tag 26 or will be detected and processed by the data tag 26. Upon detecting and processing, the drone racing system 2 updates to indicate that the drone 4 has been to a certain location. Once the drone 4 has interacted with all data tags 26, it has completed the race, and the finish time of the drone 4 will be compared to the finish time of other drones 4 to determine who wins.

In another embodiment, users of the drone racing system 2 may create a customized race track or race course with the virtual information points or other data tags 26 as navigational points. In this embodiment, participants in the drone race have the location of a first virtual information point, and upon reaching the first virtual information point, participants receive information about a second virtual information point. This pattern repeats itself and develops into a full-fledged race with a race track known only to the creator of the race track. Alternatively, the participants have the locations of all navigation points, and the drone racing system 2 provides a virtual racetrack for participants to follow through the use of an application on a computing device. The customized race track may be stored in the race server 1206 or on the computing device of the user that created it, for personal use. The user may create this customized race track by using a virtual map of the contained or designated areas, correlating to the current and actual structures and obstacles of the contained or designated areas, and assigning certain locations on this virtual map with virtual information points.

FIG. 11 is a flowchart of a method for conducting a drone race 1100, such as in a contained or designated area(s), in accordance with an illustrative embodiment. The method for conducting a drone race 1100 may be implemented in a drone race or game system, such as embodiments of the drone race or game system in FIGS. 1-14 herein. The method for conducting a drone race 1100 may include attaching a sensor to each of the plurality of drones 4 (step 1101). The temporary or non-temporary (e.g., permanent) attachment may be accomplished by any currently existing or later developed method, and the sensors may be any currently existing or later developed sensor for automatic identification and data capture techniques. For instance, the method may include attaching a camera 27 and transmitter 31 to a drone 4. The transmitter 31 may emit RF energy.

In various instances, the method may also include wherein sensor readers, such as receivers 32 are calibrated to detect the sensors, such as transmitters 31 attached to the drones 4 (step 1103). In order for a drone race or game to be conducted in a contained or designated area(s), the sensor readers, such as receivers 32 attached to obstacles need to be able to detect whether a drone 4 has passed the obstacle with a certain percentage of accuracy and precision. The calibration of the sensor readers, such as receivers 32 may be accomplished by any currently existing or later developed method. For instance, a sensor reader such as a receiver 32 may be calibrated to determine the moment in which a drone 4 passes the obstacle such as by detecting a point of inflection in a signal amplitude trend of a signal from the transmitters 31 over time, such as to designate the closest approach of the transmitter 31 to the receiver 32.

In various instances, the drones 4 may be calibrated to correspond to a computing device (step 1105). By calibrating the drones 4 to correspond to a computing device, the drones 4 may be monitored by the computing device. Like the calibration of the sensor readers, the calibration of the drones 4 may be accomplished by any currently existing or later developed method. For instance, the computing device may be configured to associate an identifying feature of a signal from a transmitter 31 associated with the drone 4. For instance, such as identifying feature may comprise one or more data bit having a value addressing the drone 4.

A customized timestamp is transmitted to a race server 1206 from the sensor readers, such as receivers 32 (step 1107). The customized timestamp may include information about a nearby drone 4, a time the drone 4 was detected, and an obstacle structure that the sensor reader, such as receiver 32 is attached to. The sensor readers such as receivers 32 may transmit the customized timestamp through a communication channel to a race server 1206, using any currently exiting or later developed method.

Lastly, a position of each of the plurality of drones 4 is determined based on the customized timestamps transmitted from the sensor readers such as receivers 32 to the race server 1206 (step 1109). Because the customized timestamps transmitted to the race server 1206 at a certain time, the system can compare the times that the multiple timestamps were transmitted to determine who passed the sensor reader earliest amongst the drones 4 in a current lap around the race track, and therefore the drone race system can determine a position for each drone 4 relative to the other drones 4. All scores and positions may be ranked and placed on a community rank board. The community rank board may be hosted with social media platform, or on the internet.

Directing attention to FIGS. 1-14, but with particular attention to FIG. 12, an example architecture 1200 of a drone racing system 2 is disclosed. A drone racing system 2 may comprise a race management environment 1201 and a race participant environment 1202. A race management environment 1201 may include aspects of the drone racing system 2 other than the participating vehicles. A race participant environment 1202 may include the participating vehicles, such as a drones 4 having sensors—for instance, a first drone 1204-1 and a first sensor 1203-1, a second drone 1204-2 and a second sensor 1203-2, and any number, n, such as an N^(th) drone 1204-n with an N^(th) sensor 1203-n.

The race management environment 1201 of the drone racing system 2 may comprise a race server 1206. A race server 1206 may interoperate with aspects of the drone racing system 2 as already discussed herein. The drone racing system 2 may be configured to transmit, receive, compile, compute, and interpret data associated with a drone race or game. Specifically, a race server 1206 may be connected via a course data channel 1213 to a course data repository 1205. The race server 1206 may send and receive data for storage via the course data channel 1213 to the course data repository 1205. This may include data representing the location of different features of a course, such as gates, hoops, starting points, ending points and the like, as well as data indicating an association between a sensor reader and a location on the course (reader location data 1212).

The race server 1206 may be connected via a sensor reader channel 1214 to a sensor reader array 1208. A sensor reader channel 1214 may comprise a wireless radio connection, an optical connection, and/or a wired connection such as via a computer network. The sensor reader array 1208 comprises a plurality of sensor readers disposed through the race or game course and associated with locations on the course (e.g., as indicated by reader location data 1212). In various instances the sensor reader array 1208 comprises a first sensor reader 1207-1, a second sensor reader 1207-2, and any number n of sensor readers such as a N^(th) sensor reader 1207-n.

The race server 1206 may be connected to a network 1219. A network 1219 may comprise a third-party network such as the internet, or an intranet, or a wireless network, or a proprietary network, or any network or combination of network technologies as desired.

The race server 1206, via the network 1219, may interconnect to a backend supervisor 1211 via a backend supervisor communication channel 1217. The backend supervisor 1211 may comprise a processor and non-transient computer readable memory configured to interoperate with multiple race servers 1206 at different race sites, such as geographically or temporally dispersed race sites, and may coordinate shared data storage and data flow among the race servers 1206. For instance, with momentary additional reference to FIG. 13, a race server 1206 may be associated with a race or a group of races and a different race server 1206 may be associated with a different race or different group of races and the various races may be desired to be combined in a shared leader board for a geographically or temporally dispersed racing league or combination of leagues in competition. For instance, a multi-league racing environment 1300 may comprise a backend supervisor 1211 connected to a first race server 1206-1 and a second race server 1206-2 within a first racing league 1301-1, and a third race server 1206-3 and any number, n, of race servers such as a N^(th) race server 1206-n within a second racing league 1301-2. The backend supervisor 1211 may coordinate leader board data among leagues to provide a shared leader board for interleague or intraleague competition.

Returning primary reference to FIG. 12, the race server 1206, via the network 1219, may interconnect to one or more race site computing device 1209 via a race site communication channel 1216. A race site computing device 1209 may be associated with an operator of a racing drone 4 and may provide various information consistent with the discussion herein, such as first-person view video, control signals, leader board data, race course data and/or the like.

The race server 1206, via the network 1219, may interconnect to one or more remote computing device 1210 via a remote device communication channel 1218. A remote computing device 1210 may be associated with a spectator of a drone race may provide various information consistent with the discussion herein, such as first-person view video, leader board data, race course data and/or the like. In various instances. The remote computing device 1210 may be associated with an operator of a drone 4 not located at a race site and may provide first-person view video, control signals, leader board data, race course data and/or the like.

Shifting primary focus to FIG. 14, a race server 1206 and/or a backend supervisor 1211 may also include a leader board coprocessor 1400. In various instances, a leader board coprocessor 1400 comprises a leader board bus 1412 having various operative modules connected to it. While in various instances the bus may be a physical bus, in further instances the bus may be a logical bus. The leader board coprocessor 1400 may comprise a bus controller 1411 connected to the leader board bus 1412 and controlling the flow of data on the bus between various modules and directing the operation of the various modules, as discussed herein.

In various instances, a leader board may include advanced and automated aspects. For instance, a leader board may be set up by class of drone 4 participating in the drone race. The leader board may be divided according to an organization scheme, such as so-called 180 mm and below, 190-300 mm, and other size drones 4 as one having ordinary skill in the art may understand drones 4 to be classifiable. Thus a leader board may comprise a drone classification engine 1413. In various instances, a drone classification engine 1413 is configured to automatically receive self-reported classification data from a drone 4. For instance, a first drone 1204-1 may self-report via a signal from first sensor 1203-1 to a sensor reader that the drone 4 belongs in a particular class.

Similarly, a leader board may be set up by age of drone operator. Once again, the drone classification engine 1413 may receive self-reported classification data including age data, such as from a first drone 1204-1 via a first sensor 1203-1 to a sensor reader, or in further instances, from a race site computing device 1209 connected to the race server 1206 or from a remote computing device 1210 connected to the race server 1206. The age data, similar to the other classification data, may be stored in a database associated with the race server 1206 such as a course data repository 1205 to classify drones 4 currently operating on the race course. In a similar way, a leader board may be set up by school associated with a drone operator, or by a league associated with a race in which a drone 4 is participating. Thus, in this manner, the drone classification engine 1413 may direct the leader board generator 1401 to display the first drone 1204-1 within a first drone class in response to self-reported classification data from a first drone 1204-1 via a first sensor 1203-1 transmitting the self-reported classification data to a sensor reader of the drone race system.

Thus one may appreciate that the leader board coprocessor 1400 further comprises a cross-site/league coordination engine 1402. The cross-site/league coordination engine 1402 interoperates with a cross-site I/O module 1407 to send and receive data among different race servers 1206 and/or to a backend supervisor 1211 so that the leader board may be shared across multiple geographically or temporally dispersed races. The cross-site/league coordination engine 1402 sorts data received from other sites via a cross-site I/O module 1407 and prepares data for transmission to the other sites via the cross-site I/O module 1407. The cross-site I/O module 1407 formats the data according to a known format and instantiates transmission and reception request directives to initiate and/or conclude data exchanges. In various instances, a back end supervisor I/O and relationship store 1410 is further implemented to cache a local copy of data from other race servers 1206 and from backend supervisors 1211, such as for use in an offline race environment wherein the race is at a site disconnected from external network resources.

A leader board may display various data metrics about one or more drone 4 participating in a drone race or game. A leader board may comprise a data type, such as a leader board object, for ease of transmission by the leader board coprocessor 1400 of data among other system aspects. For instance, the leader board coprocessor 1400 may transmit various data via a race data channel controller 1408 to a network 1219 for distribution to race site computing devices 1209 or remote computing devices 1210. For instance, an application may be loaded on a smartphone and receive from the race data channel controller 1408 a visual depiction of a race course to allow an operator to fly a simulated lap through a race course without actually operating a physical drone 4 in the course. Moreover, the race data channel controller 1408 may provide data wherein an operator may search for and follow the activities of other operators, watch recorded races stored in a historical race data store 1409 of the leader board coprocessor 1400, and engage in discussions and posting comments.

The leader board coprocessor 1400 may use the race data channel controller 1408 to automatically publish results of races to other resources, display race segments or laps, allow comparison with other races on a same course, replay historical race video and source other static or dynamic data as desired (collectively, “Event Data”). Such other resources may include, for instances, a backend supervisor 1211, a course data repository 1205, or automatic publication may be made directly to race site computing devices 1209 and remote computing devices 1210, and/or to a historical race data store 1409 for later retrieval. Such results may include both real-time and non-real-time data, including drone geopositioning during races, geopositioning of races occurring on other race servers 1206 throughout the world, social media transmissions including automatic results posts, videos, event winner identity, and/or the like (also collectively, “Event Data”). Thus a leader board coprocessor 1400 may further comprise wherein the race channel controller 1408 is further configured to transmit the leader board object to the network for distribution to at least one social media account wherein the leader board object is configured to update the at least one social media account with an event data. In various instances, such event data is shareable via social media.

In various instances, the leader board coprocessor 1400 provides for automatic set up and on-the-fly reconfiguration of race courses and race participant information. For instances, the system may automatically learn the identity of participating drones 4, add drones 4 as the drones 4 appear at a starting point of a race, such as based on identifying addresses, frequencies, etc. associated with the drone 4, and may maintain a leader board over time. For instance, a leader board generator 1401 may instantiate a leader board as discussed herein. The leader board generator 1401 may solicit a drone instantiator 1403 to interoperate with the race data channel controller 1408 for receiving communication from sensor readers to count and identify drones 4 on the racing or game course. In various instances, the drone instantiator 1403 triggers the leader board generator 1401 via a message on the leader board bus 1412 to add a new drone 4 to a leader board. Thus the system further includes instantiating, by a drone instantiator 1403, a second drone 1204-2 for insertion into the leader board object in response to detecting by the sensor reader a second drone 1204-2.

Similarly, the system may automatically learn the identity of participating drones 4 and remove drones 4 as the drones 4 no longer appear at a point in the race, for instance, by failing to be detected by a sensor detector due to a crash, and/or by being detected at a stationary orientation during a drone race or game. In response to a drone 4 identified based on identifying addresses, frequencies, etc. associated with the drone 4, being determined to be inoperative, stationary, or having failed to be detected for a period of time, the drone departure engine 1406 may direct the leader board generator 1401 to remove a drone 4 from the leader board. For instance, a leader board generator 1401 may instantiate a leader board as discussed herein. The leader board generator 1401 may solicit a drone departure engine 1406 to interoperate with the race data channel controller 1408 for receiving communication from sensor readers to count and identify drones 4 on the racing or game course. In various instances, the drone departure engine 1406 triggers the leader board generator 1401 via a message on the leader board bus 1412 to remove the drone 4 from the leader board.

The system may also automatically learn the location of different sensor-readers on the race course or game. For instance, a sensor-reader mapper 1404 may interoperate via the race data channel controller 1408 with the different sensor readers of a sensor reader array 1208. By mapping the relative rise and fall of the signal strengths of the transmitted signals transmitted from the different drones 4 by each drone's sensor, a map may be developed over time of the relative locations of the sensor-readers in response to the relative rise and fall of the signal strengths as the drones 4 traverse the course.

Finally, the system may conduct race timing. For instance, a timing engine 1405 may interoperate via the race data channel controller 1408 with the different sensor readers of the sensor reader array 1208. The timing engine 1405 may monitor characteristics of the transmitted signals transmitted from the different drones 4 by each drone's sensor and ascertain a moment of closest approach of each drone 4 with each sensor receiver 32, thus determining the time at which the drone 4 passed the sensor receiver 32. As such, the system may time, by the timing engine 1405, a race of a first drone 1204-1 and a second drone 1204-2, in response to ascertaining at least one amplitude peak of a first transmitted signal of the first drone 1204-1 by at least one sensor reader and at least one amplitude peak of a second transmitted signal of the second drone 1204-2 by the sensor reader.

As indicated above, aspects of this invention pertain to specific “method functions” implementable through various computer systems.
